per volume (liter/gallon) is determined by the Pulser unit. It is
programmed as a "factor" by the Head Office controller.
Handle Status Input
Wires: The handle signal is used to signal the system that the pump is "In Use"
mode. When the dispenser handle is lifted this contact will close. This
should signal the system that the pump is "In Use" or that the transaction
ended.
Authorization Output
Wires: The dispenser requires an authorization signal from the Islander PLUS to
start a sale transaction. Without this authorization signal, the electric valve
(or pump) will not open and the sale transaction will not begin. The
Islander PLUS switches the AC power signal to the valve. When the
dispenser receives the authorization signal, fuel is flowing.
NOTE
All terminal block references and numbers in the
following drawings (up to figure 3.27) refer to
Islander PLUS with 4 pumps only.
